Find the circumference of the circle. Round to the nearest tenth if necessary.

A. 21 m

B. 66 m

C. 132 m

D. 264 m

Answer:

c.132

Step-by-step explanation:

so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**

but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**

so we have to divide 42/2 which equals 21

now we need to set up the formula;

c=2πr/c=2xπxr  **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**

c=2π21

=131.946891451

and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132

good luck :)

i hope this helps

have a good one !!

Which steps would you use to solve this equation? Check all that apply.

p + 7 = 12

Subtract 7 from both sides of the equation.
Subtract 7 from 7.
7 – 7 = 0 and 12 – 7 = 5, so p = 5.
Substitute 12 for p to check the solution.
Substitute 5 for p to check the solution.
